  • Altimetric Mechanical Counter

    Altimetric Counters

    LEMANS AVIONICS Altimetric Counters are specially designed for mounting in mechanical altimeters with aneroid capsules. They provide a precise and understandable display of the altitude thus being a key element in altimeters. Each counter is composed of several drums rotating over a main axis under the change of the atmospheric pressure due to the altitude change. The drums are linked through a fine mechanical gearing system providing a higher precision than the most precise of mechanical watches.
    Barometric Mechanical Counter

    Barometric Counters

    The Barometric Counters manufactured by LEMANS AVIONICS are a reference in terms of quality and robustness. Most mechanical altimeters have a barometer function. Thus there is a need for a Mechanical Counter for the display of the barometric value. These counters can be edited in Millibar Units as well as In-Hg Units. They can also be delivered with standard or fluo screening as well as in all standard printings.
    clean-room assembling

    Cockpit Clocks

    Through its years of experience in manufacturing counters, LEMANS AVIONICS has developed a precious know-how in the assembling of high precision mechanical components. Therefore, LEMANS AVIONICS offers now the manufacturing of Cockpit Clocks sub-assemblies. Elements are assembled by our highly-qualified staff and in clean-room facilities offering a great quality for sub-assemblies as basic clocks and chronographs.
